Gold is a precious metal that has a long and interesting history. Gold has set the standard throughout the ages as being the metal of choice for fine jewelry, elaborate decorations and a form of money. Most gold found today is in the form of different pieces of jewelry. However, gold can also be found in a variety of things.
Gold is used in dentistry because of its superior performance and aesthetic appeal. Gold alloys are used for fillings, crowns, and bridges. Gold is a perfect metal for use in dentistry because it is chemically inert, non-allergenic and easy for dentists to work with. Gold was used generously in dentistry up until the late 1970's. Substitute materials were developed due to the soaring price of gold at that time. There is starting to be an increase in the use of gold today.
Gold is also used as a drug to treat a small number of medical conditions. Injections of weak solutions which contain aurothioglucose are sometimes used to treat rheumatoid arthritis. Particles of radioactive gold isotope are implanted in tissues to serve as a radiation source for treatment of some cancers. Radioactive gold is also used in diagnosing certain conditions.
You can find gold in many surgical instruments, electronic equipment and life support devices. The reason they use gold is because it is nonreactive in surgical instruments and is highly reliable for life saving devices used in hospitals.
Gold is used in hundreds of ways in every space vehicle that NASA launches. This is because gold is an extremely dependable material. Many parts of a space vehicle are fitted with gold coated polyester film, which reflects infrared radiation and helps control the temperature of the spacecraft. Gold is also used as a lubricant between mechanical parts.
Gold is also used in the production of glass. Gold is used when making specialty glass for climate controlled buildings and glass cases. The use of a small amount of gold which is dispersed in the glass or coated onto the glass surface will reflect solar radiation which helps the building stay cooler. This same type of gold coating is used on the helmet of an astronaut's space suit. It reflects much of the very intense solar radiation and protects the astronaut's eyes and skin.
Since gold has the highest malleability of any metal it can be beaten into thin sheets, which are known as gold leaf. This can then be applied over irregular surfaces such as picture frames, molding or furniture. Gold leaf can also be found on the exterior of buildings because it provides a durable and corrosion resistant covering. It is also very appealing to the eyes when it appears on domes of buildings such as religious or important structures.
Gold is a very durable and versatile metal that is found in many things. Gold jewelry and gold coins are just some of the things that are made of this precious metal. Gold has a long history and probably will still be around at the end of time. That is why it is important to recycle old and broken jewelry so we can save are natural resources for generations to come. - 30311
